Question 15

Question text

Choose the correct sentence where the past progressive is appropriately used:

Select one:

a. He was driving to work when he calling me.

b. When he called me he was driving to work.

This is incorrect. The sentence doesn't have a comma to separate the DEPENDENT CLAUSE to INDEPENDENT CLAUSE. A comma is placed after the When-clause if it is placed before the main clause. The comma marks the separation of the two clauses.
